. Application filed November 8, i916. Serial No. 130,198.

Toall whom it may concern:

Be it known thatl, Bonner B. Coon, a

citizen of the United States, residing at "Lancaster, in thecounty ofFairfield and 4 State of Ohio, have invented certain new .and usefulImprovements in Gas-Burner Attachments, of which the following is aspecification.

This invention relates to devices inqwhich.

inflammable gases are employed as a fuel, and has for one of its objectsto provide a simply constructed device adapted to be utilized incoaction with various forms of gas burners, more particularly devices ofthis character forming a part of gas cooking stoves, ranges and thelike, to economize in the use of the gas.

in the claims; and in the drawings illustra tive of the preferredembodiment of the invention- Figure 1 is a plan vlew of the improveddevice.

Fig. 2 is a transverse section on the line 2-2 of Fig. 1. I

Fig. 3 is a view similar to Fig. 2, illustrating a modification in theconstruction.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The improved device includes an annular outer member represented as awhole at 10 and having, vertical sides, or in band shape, with aplurality of recesses 11 in its lower edge to provide for the freepassage of air between the member 10 and the structure upon which. itrests. The improved device is designed to be located upon the upper faceof a stove or range in which gas is employed as a fuel, with the rimportion 10 entirely inclosing the burner, not shown. Located centrallyof the rim portion 10 is a portion including a ring or annular member12, a central hub 13 and a plurality of radial bars 14 connecting themembers 12-48, as shown in Fig. 1. The upper faces of the members thegas.

12l314: are on the same level and are I located above theupper line ofthe member 10, as shown in Fig. 2.

Extending between the rim member 10 and the annular member 12 is aninwardly and upwardly curving web indicated as a whole at 15, andprovided with a plurality of apertures 16 for the upward passage of Thelower face of the web thus curves constantly inwardly and upwardly andmerges without obstruction into the annular central portion. The web 15is united at its outer periphery to the member 10. near itslower edge,as shown in Fig. 2, so that the member 10 projects for a considerabledistance above the outer portion of the web, and forms a guard to theburning gas as it rises through the apertures 16.

The vessel whose contents are to be heated by the burning gas is locatedupon the member 12 as indicated by dotted lines 17 and the rising flamesand heat products impinge against the lower face of the web and themajor portion passes without obstruction through the annular centralportion 12, while the remaining portion of the flame and heat productspass upwardly through the apertures 16 and impinge against the bottom ofthe vessel and all of the flame and heat products are deflected therebyover the upper edge of the member 10, the latter thus operating as aguard to prevent the dissemination of the gas by confining the gas tothe space within the area of the member 10, and causing it to remain incontact with the vessel supported, as above described, upon themember12.

The vertically directed guard rim 10 is thus an important feature ofapplicants device and materially increases its efficiency and utility.

The improved device is constructed from a single casting, preferablyannealed to enable it to withstand the heat to which it will besubjected when in use, and may be of any required size to adapt it tothe burner or construction of the stove with which it is to coact. 7

If preferred the device may be constructed as shown in Fig. 3. v

Having thus described the invention, what is claimed as new is 1. Adevice of the class described comprising a body adapted to be disposedover a burner and including an annular outer portion with vertical sidesand an annular central portion, said annular central portion extendingabove the upper line of the annular outer portion, and a perforated webconnected to the annular outer portion near its lower edge and curvingconstantly inwardly and upwardly and merging Without obstruction intothe annular central portion, where by the major portion of the, namesfrom the burner is guided. inwardly and upwardly toward and caused topass through the anportion.

2. A device of the class deseribedcomprising a body adapted to bedisposed over a Copies 'of this patent'may be obtained for burner andincluding an annular outer portion with Vertical sides and an annularcentral portion; and a perforated web connected to the annular outerportion near its lower edge and curving constantly inwardly and upwardlyand merging Without obstruction into the annular central portion,whereby the major portion of the flames from the burner is guidedinwardly and upwardly toward and caused to pass through theani Intestimony whereof I afliX mysignature.
